    Addressed issues with EditText causing scroll
   
    EditText methods: bringPointIntoView, and handleFocusGainInternal
    trigger requestChildRectangleOnScreen in ViewPager2's internal
    RecyclerView.
   
    This can cause:
    - unwanted scrolling -- e.g. when typing on some API versions
    - a jump to page 0 -- EditText sometimes reports over -1M px mScrollX
   
    This fix bypasses requestChildRectangleOnScreen calculations taking
    advantage of the fact that PagerSnapHelper constraints valid scroll
    values to a snapped position ones, and as a result, the problem is
    reduced to choosing the correct currentItem.
